HEAD-MOTION FOR LOOMS.

Specification of Letters Patent.

Patented Get. 14,1 913.

Application filed November 11, 1912. Serial No. 730,571.

To 077 whom it may concern:

Be it known that I, Erna H. Bron, a citizen of the United States,residing at Waltham, in the county of Middlesex and State of hlassachusetts, have invented certain new and useful Improvements inHead-Motions for Looms, of which the following is a specification.

My invention relates to a head motion for looms, and more particularlyto the head motion for looms of the Knowles type, shown and described inReissue Letters Patent, No. 7784, in which vibrator gears are movedaccording to the pattern surface, into mesh with the upper and lowercylinder gears, and rotated thereby in one direction or the other, tooperate the harnesses, or drop boxes.

The object of my invention is to provide means for positively operatingthe vibrator levers, to positively raise and lower said vibrator leversby intermediate cam vers, which are positively rocked or operated by thepa tern chain, and to lock said vibrator levers in each position inwhich they are moved.

My invention consists in certain novel features of construction of myimprovements as will be hereinafter fully described.

Referring to the drawings :-Figure 1 is a central cross section, throughthe Knowles head above referred to, with my improvements appliedthereto. Fig. 2 shows some of the parts shown in Fig. 1, in a differentposition. Fig. 3 is a section, on line 3, 3, Fig. 2, looking in thedirection of arrow a,

sametigure, and, Fig 4 is a section, on line 4, l, Fig. 2, looking inthe direction of arrow 7), same figure.

in the accompanying drawings, 1 is a portion of a loom arch, iavingmounted thereon the stand or head frame 2, which supports the severalparts of the head motion. The head motion, of the well known .Snowlesreferred to, comprises the upper cylinder gear 3, fast on the cylindershaft t, the lower cylinder gear 5, fast on the cylinder shaft 6, thevibrator lever 7, which is pivoted at one end on the stationary rod 8,and carries the vibrator gear 9, located intermediate the cylinder gears3 and 5, and which is raised and lowered by the pattern mechanism, to behereinafter described, to communicate a reciprocating motion to theharness levers, not shown, through the vibrator connector 10.

11 and 12 are guide combs, adapted to prevent the vibrator levers frommoving sidewise. In this instance, on a stand 13, is a rotary patternchain cylinder 14, on w iich is supported the usual pattern chain, whichis made up of rolls 15 and tubes 16, in the usual way.

All of the above mentioned parts may be of the usual and well knownconstruction.

i. will now describe my improvements.

Extending over the pattern chain cylinder 14, and the pattern chainthereon, are in this instance two indicator levers 17 and 18, for eachvibrator lever 7, said indicator levers 17 and 18 have their hubspivot-ally mounted on a transverse rod 19, which is carried in hearingson the frame 13. Guide combs 20 and 21 prevent the indicator levers frommoving sidewise. The ends of the levers 17 and 18 are recessed at 17 and18, to loosely receive the lower ends of two upwardly extending inclinedrods or bars 22 and 23. The upper end of the rod 22 is pivotallyconnected to a stud 24:, on on end of a horizontally extending arm 25 onthe hub 25 of the upwardly extending cam lever 25. A second horizontallyextending arm 25, on

the huh 21")", has a stud 26 thereon, to which is pivotally connectedthe upper end of the upwardly extending rod 23. The cam lever 25 has itshub 25 loosely mounted on a transverse rod 27, which is suitably mountedin bearings 28 at each end thereof, which bearings are adjustahlysecured to the frame 2. The alternate raising and lowering of the twoindicator levers 17 and 18, by a roll,

under one lever, and then the other lever, causes the cam lever to bepositively moved into the positions shown in Figs. 1 and 2. The upperend of the cam lever has the enlarged head 25, with a cam shaped slot 25therein, into which extends a roll 29, mounted on a stud 29 attached tothe vibrator lever 7. The rocking of the lever 25, and the moving ofsaid lever from the position shown in Fig. 1 to the position shown inFig. 2, or vice versa, causes the vibrator lever to move upwardly ordown wardly; and also to positively lock said vibrator lever 7 in eachposition, without using separate locking means.

It will be understood that the details of construction of myimprovements may be varied if desired.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. In a head motion for a loom, upper, andlower cylinder gears, a vibrator gear mounted on a pivotally mountedvibrator lever, and said vibrator lever, a pattern chain, two patternindicator levers for each vibrator lever, said indicator levers operatedby said pattern chain, connections intermediate said indicator leversand said vibrator lever, to positively move said vibrator lever in twodirections, through the direct action of the pattern chain.

2. In a head motion for a loom, upper, and lower cylinder gears, avibrator gear mounted on a pivotally mounted vibrator lever, and saidvibrator lever, a pattern chain, two pattern indicator levers for eachvibrator lever, said indicator levers operated by said pattern chain,and connections intermediate said indicator levers and said vibratorlever, to positively move said vibrator lever from one position toanother, and lock the same in each posit-ion, through the action of thepattern chain.

3. In a head motion for a loom, upper, and lower cylinder gears, avibrator gear mounted on a pivotally mounted vibrator lever, and saidvibrator lever, a pattern chain, two pattern indicator levers for eachvibrator lever, said indicator levers operated by said pattern chain,and connect-ions intermediate said indicator levers and said vibratorlever, to positively move said vibrator lever in two directions, throughthe direct action of the pattern chain, said connections including alocking cam lever suitably supported.
